bob schieffer today spoke with defense secretary chuck hagel about u.s. military options. bob, what did he have to say? >> reporter: i'll tell you, bob, it was just before the president spoke and he pointedly told me it would be a mistake if the russians moved forces into other parts of ukraine. what would we do if the russian forces started rolling into other parts of ukraine? >> well, i won't get into the different specific options, but this could be a very dangerous situation if this continues in a very provocative way. we have many options, like any nations do. we're trying to deal with the diplomatic focus. that's the appropriate, responsible approach. >> reporter: hagel was circumspect, for obvious reasons, but it was clear that what he and other western officials are telling their russian counter-parts is, look, it is in no one's interest to let this get beyond where it is now. we've got to work together to try to calm this down. now, whether that message is being heard is the part that's not clear. >> pelley: bob, thanks very much. bob will have much more with secr
